Element supports clients with their annual monitoring of biogas engine and flare emissions from their plants. We assess whether releases of NOx, CO, VOC, and SO2 are within the permitted values.

Biogas is fast becoming a significant contributor to supplying green energy in the UK and across the world. The methane (or more precisely: biomethane) produced when organic matter is converted to biogas is either used as a fuel source or destroyed by flaring. The Environment Agency regulates both processes, and operators who use biogas/biomethane as a fuel source must perform emissions monitoring to ensure they comply with their permit.

Operators are required to test engine and flare emissions from their plant typically annually to assess whether NOx, CO, VOCs and SO2 releases are within the permitted values. Element can guide you through the steps necessary to achieve a successful monitoring campaign. Using an holistic approach, and working closely with site personnel and other service providers, Element can:

  • highlight any possible obstacles before conducting the monitoring, and
  • advise on best practices to ensure the testing program runs as smoothly and as cost-effectively as possible.

This approach has proven extremely successful with our clients, many of which have gained monitoring knowledge they did not previously possess.

Biogas and flare emissions monitoring – The Element advantage

Element has been working with a range of biogas and waste operators for many years. We currently supply emissions monitoring for clients ranging from large landfill and waste water operators to small sites running single anaerobic digestion engines.

The knowledge and experience we’ve built in our UKAS ISO/IEC 17025 accredited laboratories, enable us to support operators in successfully meeting their permit obligations.
